What we hold to
We make one category of thing and we would rather make it slowly. Five bonded layers with a fibre interlayer. Fourteen days of curing before a ball leaves the rack. Three diameters, because bodies are three different heights.

91 notesWriting
Height charts assume average proportions. Almost nobody has them. A better method takes one measurement and thirty seconds.
Read thisFive layers, one fibre interlayer, fourteen days of curing. What is actually inside the thing you sit on.
Read thisA short, unambitious sequence. Mobility before strength, breath before either.
Read thisWhy an unstable seat changes how you breathe, and how to use that rather than fight it.
Read thisAll-day ball sitting is bad advice. Twice a day for twenty minutes is good advice. The difference is fatigue.
Read thisA ball that needs topping up every fortnight is not necessarily faulty. Here is how to read it.
Read thisBefore you order
Measure your inseam, not your height. 71–78cm takes the 55, 79–88cm takes the 65, 89cm and above takes the 75. Then sit on it: hips level with or just above the knees. The sizing piece covers the exceptions.
The shell needs to stretch. Fill to roughly eighty per cent, leave it a day at room temperature, then top up. Going straight to full diameter thins the material permanently.
Yes. Each batch is dyed in a single run and we do not colour-correct between runs. Two balls bought a year apart will not match exactly.
Two years on the shell against pressure loss in normal use. Pumps and plugs are replaced at any age, free. Heat, solvents and unsealed concrete are not covered.
At any age, yes — we take it to the specialist recycling stream. It costs us and not you, which seemed like the right way round.
We do. Send the quantity and the size split and we will come back with trade terms and a lead time.
